TO ALL WHOM IT MAY CONCERN Be it known that I, HENRY LOMB, of the city,county, and: State of New York, have invented a new and usefulImprovement in Eye-Glasses and Spectacles; and I do hereby declare thatthe following is a full and exact description thereoQreferenee being hadto the accompanying drawings, and to the letters of reference marked,4thereon, of which- Figure 1 represents an eye-glass with my improvementthereon.

Figure 2 represents a spectacle, showing my improvement, a a.

Figure represents an enlarged section of an eye-glass frame, withnose-piece, a.

The object of my invention is to improve eye-glasses or spectacles, soas to secure a firm, and at the same time easy and comfortable .hold onthe nose, by s o constructing the frame as to make it readily adaptitself to any nose, of whatever shape, and making it easily adjustableto the variable relative position of the eyes.

The construction hitherto in use, of this kind of eye-glasses orspectacles, has been such as to secure the necessary hold on the nose inbut an imperfect manner, always subjecting the wearer to anuncomfortable and irritating Apinchon the organ in question, owing,inpart, to the smallness of the'surface on which the whole pressure of thespring is exerted, and partly to the hardness and rigidity of thematerial inimmediate contact; some-could not at all, and some'only withmuchlabor, be made properly to suit the different widths of eyes.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

I take two strips (marked a a in drawings,) made of softIndia rubber, orof material equally' yielding and elastic, which strips a a I shall callnose-pieces, and aix them, one to each lens-frame, hollow, or in such amanner as to. allow suicient space between the nose-pieces a a andlens-frames'b b, iigs. 1, 2, and 3, to enable the pieces a a toyieldaccording to their' elasticity, so as to conform to the shape of,the nose, thus securing a firm hold thereon to the entire extent of thelength of the -nose-pieces a a, and so preventing a concentration of thepressure on any isolated or particular point, which latter is the case`with all eye-glasses or spectacles of this kind constructed after theusual plan, which only touch the nose in a tangential manner. Thefastening of the elastic nose-pieces a a to the .lens-frames b b may beeffected in various well-known ways. I prefer to fasten the upper end ofcach nose-piece by means of one or moroscrewsxat 0l d, to thelens-frame. The .lower end of each elastic strip forming thenose-picces'a a, may either 4.he secured to the respective lens-frame in the samemanner, by one or morel screws, or it-may be slipped throrsglra smallloop or band, y, attached to the lensframe, so as to admit of theenlargement or decrease of the spaces e c, by drawing the elastic stripsa a (which must be left of sncient length for such purpose,) either way`through such loops, so as to increase or decrease the distance betweenthe nose and the lens-frames, `in order to bring tlecentre of each lensrespectively opposite the centre of the corresponding eye, in accordancewith thelaws of vision.

What I claimas my invention, and desire to secure by Letters Patent, is

The elast-ic bandsor straps a, in combination with an eye-glass orspectacle-frame, when such bands or straps are fastened to the frameonly at or near their ends, and between such points are left free of theframe. with an opening or space between, substantially as described forthe purpose specified.
